Thanks, Matt. Good morning, everyone and thanks for joining us today. I am delighted to announce our Q1 results this morning. Maintaining last year’s momentum we are off to a tremendous start this year, as demonstrated by the continued strong business performance, initiation of IW-3300 and CNP-104 clinical studies and another quarter of delivering profitability and positive cash flow from operations. At Ironwood, we remain committed to advancing the treatment of GI diseases and redefining standard of care for GI patients. We are focused on driving value for our shareholders by bringing important medicines to our patients. I believe the progress we have made across the organization in the first quarter demonstrates the steps we are taking to become the leading GI healthcare company in the U.S. Now, I will begin with a brief overview of our strategic priorities on Slide 6. Our strategy starts with maximizing LINZESS. We continue to be excited by the performance of LINZESS, which has delivered another quarter of double-digit demand growth, and we believe there is more opportunity ahead. Beyond LINZESS, we are making progress on our clinical trials and remain on track with previously shared data readout timing. We are focused on strengthening our pipeline through our in-license and acquisition of innovative GI assets, which we believe will position our company for continued growth. And finally, we continued to deliver sustained profits and cash flow. We ended the first quarter with approximately $593 million in cash and cash equivalents on the balance sheet and we continued to execute on our Board-authorized share repurchase program. Through the end of March, we have repurchased $118 million in our common stock. You see these achievements in the first quarter as important progress that we believe will support the continued growth and success of our company. Now, let’s turn to some additional details on the commercial performance of LINZESS starting on Slide 7. It’s hard to believe that 2022 represents year 10 of LINZESS being on the market. LINZESS has grown from being the first-in-class GC-C agonist, becoming the number one prescribed branded treatment in the U.S. for adults with IBS-C and chronic idiopathic constipation. As you can see on the slide, LINZESS is a leader in the category with an 83% share and a 75% total prescription share with gastroenterologists in the branded IBS-C and chronic constipation market. LINZESS is also the leader in the combined branded and generic IBS and chronic constipation market with a 43% total prescription share. Most importantly, we are proud to have supported nearly 4 million unique patients with LINZESS since the launch of the brand in 2012. Building on last year’s momentum, LINZESS prescription demand increased an impressive 11% year-over-year in the first quarter of 2022 as shown on Slide 8, continuing the stretch of five consecutive quarters of double-digit prescription demand growth. In addition, 90-day prescriptions have grown as a percentage of total retail prescriptions with an all-time high of 21% at the end of Q1. This has also helped increase the average prescription size of LINZESS to roughly 43 days. Slide 9 provides a bit more color on what we believe are the key drivers of LINZESS demand over the long-term. It starts with a strong clinical profile. LINZESS, as FDA-approved labeling, demonstrates the improvement of overall abdominal symptoms of bloating, pain, and discomfort in adults with IBS-C, and we are committed to helping both patients and providers understand the importance of treating these symptoms beyond constipation. Additionally, the American College of Gastroenterology guidelines strongly recommend GCC agonists, including LINZESS to treat IBS-C symptoms and recognize the high-quality evidence supporting LINZESS. Moving to patient activation, LINZESS continues to lead the IBS-C and chronic constipation branded prescription market and direct-to-consumer promotion with the goal of educating more appropriate adult patients to seek care for IBS-C versus continuing the frustrating cycle of self-managing with over-the-counter therapies. In April, we, together with our partner, AbbVie, launched our newest consumer campaign, which performed extremely well in market research. Of course, patient activation is not possible without the care of physicians and other healthcare professionals. At Ironwood, we are a GI healthcare company with an experienced and highly skilled sales force focused on broadening the use of LINZESS to gastroenterologists and high-volume primary care physicians for appropriate patients. In addition, our investment in payer access is helping support clinical decisions by healthcare practitioners. We are proud that after many years, LINZESS has class-leading payer access and is widely available on commercial and Medicare Part D formulary. By looking at key plans, LINZESS is preferred on the top-end commercial plans. It is covered or better on the top 7 Medicare Part D plans. Net-net, most patients who need LINZESS get chosen by their healthcare professional. Finally, we believe we can expand the clinical utility of LINZESS through key lifecycle management initiatives, including our ongoing pediatric program. Over time, we continue to refine our marketing mix and invest in the brand to support brand growth and improve brand margins and cash flow generation. We remain focused on the levers that we believe will drive continued demand growth and in turn generate profits and cash flow. Looking ahead, we are excited about continuing to maximize LINZESS, advancing our clinical programs, strengthening our financial position, and growing Ironwood’s leadership position within GI. In a few weeks, we will be presenting 8 abstracts at the Digestive Disease Meeting or DDW, 2 of which are oral presentations highlighting our commitment to advancing the science as we strive to deliver better therapies for patients suffering from GI diseases. In particular, we will be presenting new data on the clinical utility of the abdominal score, which is important to help physicians better understand the symptoms most important to patients suffering from functional GI disorders. We look forward to DDW and sharing data on linaclotide as well as preclinical IW-3300 data with the brightest minds in the GI community. I would like to say a big thank you to all Ironwood employees who have laid the groundwork for continued momentum and strong execution against our strategic priorities as we continue to help make a remarkable impact on patient lives. I would now like to hand the call over to Mike who will discuss our pipeline programs.

Thanks, Tom. I will start with the linaclotide pediatric program on Slide 11. The clinical studies are ongoing and we continue to expect the functional constipation study in 6 to 17-year-olds to read out in the second half of this year. The study is utilizing a 72 microgram dose and evaluating the safety and efficacy of linaclotide over a 12-week period in comparison to placebo, with spontaneous bowel movement as the primary endpoint. This is an exciting opportunity to potentially expand the clinical utility of LINZESS and assuming positive data and FDA approval bring a new treatment option to this patient population as there are currently no FDA-approved prescription pediatric therapies for functional constipation. Thanks for advancing IW-3300, a guanylate cyclase-C agonist and a wholly owned asset for the potential treatment of visceral pain conditions, such as interstitial cystitis, bladder pain syndrome, and endometriosis. The single ascending dose study completed in the first quarter of this year would test the safety and tolerability in healthy volunteers. Based on the successful completion of that study, we are now planning to kick off the multiple ascending dose study in quarter two. Consistent with prior guidance, we expect to start the Phase 2 proof-of-concept study at the end of this year that will focus on pain benefits in IW-3300 for patients suffering from interstitial cystitis and bladder pain syndrome. We are currently working to finalize the study design. We recently had an advisory board meeting on this program and the urologists we spoke with were really excited about the preclinical evidence for IW-3300 and relief of visceral pain in a number of preclinical models. And lastly, CNP-104, COUR Pharmaceuticals is currently conducting a clinical study of CNP-104, and the data is on track to be out in 2023. The study is evaluating the safety, tolerability, pharmacodynamics, and efficacy of CNP-104 in patients 18 to 75 years of age with PBC who are unresponsive to URSO and Ocaliva. The endpoints include pharmacodynamic outcomes such as a change in Alkaline Phosphatase, which has been the foundation of prior product approvals. The real compelling feature is the objectivity of the immunological outcomes for this study as well as the specificity of the therapy. The parent diagnosis of PBC includes a positive anti-mitochondrial antigen, which is the immune response to the target of this therapy, the PBC-E2 antigen. So clinically, we’re identifying the right patients to treat in this study. We’re thrilled to collaborate with COUR on CNP-104, which we believe has the potential to significantly shift the treatment paradigm in PBC away from symptom management and be the first disease-modifying therapy for PBC patients. With that, I’ll now turn it over to Sravan to review our financial performance.

Thanks, Mike, and good morning, everyone. I would like to provide a few updates this morning. First, I will highlight our first quarter performance. Then I’ll discuss our capital allocation strategy. And finally, I’ll review our 2022 guidance. Please refer to our press release for our detailed financial information. I’ll start on Slide 13. LINZESS U.S. net sales were $232 million in the first quarter of 2022, an 8% increase compared to the first quarter of 2021. Net sales growth was driven by continued strong prescription demand, partly offset by net price erosion. In Q1, we experienced more modest net price erosion than anticipated due to a one-time gross-to-net benefit. From time to time, we may have one-time adjustments related to contracts or estimates as a normal part of the gross-to-net process that can have a quarterly impact, but that does not alter our full year expectations. Therefore, for the full year, we continue to expect LINZESS U.S. net sales growth in the low single digits, driven by double-digit prescription demand growth. Turning to LINZESS brand profitability, commercial margin in the first quarter of 2022 was 74% compared to 73% in the first quarter of 2021. Moving to Ironwood revenues. In the first quarter of 2022, Ironwood revenues were $98 million, up 10% year-over-year, primarily driven by U.S. LINZESS collaboration revenues of $94 million. Turning to income tax expense. During the first quarter of 2022, Ironwood recorded $17.7 million of income tax expense, the majority of which was non-cash as Ironwood continues to use net operating losses to offset taxable income for federal purposes and in many states. As a reminder, Ironwood has significant net operating loss carry-forwards from prior years, and therefore, the majority of our income taxes will be a non-cash expense as we use our net operating losses. Moving to Ironwood’s profitability, GAAP net income was $39 million and adjusted EBITDA was $58 million in the first quarter of 2022. Before moving on, I’d like to point out that beginning in the first quarter of 2022, we adopted ASU 2020-06, the new convertible debt accounting standard, which has the effect of decreasing our non-cash interest expense and increasing the number of shares used in the computation of our diluted earnings per share. It’s important to note that the adoption of this accounting standard does not affect cash flows or adjusted EBITDA. Please refer to our public filings for additional information on this change. Now moving to cash and capital allocation priorities, in the first quarter, we generated $64 million in cash flow from operations and ended the quarter with $593 million in cash and cash equivalents. We continue to execute on our Board-authorized share repurchase program of up to $150 million that runs through the end of this year. Through March 31, we repurchased $118 million of shares. And we’ve repurchased an additional $16 million of shares through April 30, 2022. Lastly, we have elected to settle the $121 million 2022 convertible note that matures on June 15 in cash. With a strong balance sheet and disciplined approach to capital deployment, we are well positioned to create value for our patients and shareholders by maximizing LINZESS and actively pursuing innovative, highly differentiated GI assets to bolster our portfolio. Next, our 2022 guidance on Slide 14, we are reiterating our full year 2022 financial guidance as we remain confident in the continued strength of LINZESS with expectations of double-digit prescription demand growth. While we had a strong performance in Q1 due to the previously mentioned one-time net price benefit, we continue to expect U.S. LINZESS net sales growth in the low single digits for the year. As such, we continue to expect Ironwood revenue of $420 million to $430 million, which includes approximately $10 million in royalty and other revenues and adjusted EBITDA of greater than $250 million. Looking ahead, we remain focused on advancing our three strategic priorities. We’ve built a strong foundation, and we are excited about the opportunities ahead of us to improve the lives of GI patients and deliver shareholder value. I want to close by thanking all of our employees, patients, caregivers, and advocates for their shared dedication to advancing and supporting therapies for GI disorders.

Operator, you may now open up the line to questions.

Hi, good morning. This is Hannah on for Eric. Thanks for taking the questions. So just first on the pediatric opportunity for linaclotide. You have the trial currently going on with data expected towards the end of this year. Can you talk a little bit about your expectations for the study? What would you consider as a win or label-expanding data with respect to SBM? And then on the potential design of a Phase 2 proof-of-concept study for IW-3300. Just wondering, in general, if we might see any changes in the product in the near-term or down the line because while you’re initially evaluating a suppository formulation, are there any plans to revisit that? And also, if so, what are the steps to making that happen? Thanks for taking the questions.

Well, good morning, Hannah. Thank you for your questions. I’ll hand it over to Mike Shetzline to answer them.

Yes. Thanks for the question. So the peds program, as you may know, was developed on the back of a Phase 2 study. So we did a Phase 2 study and actually enrolled about 173 pediatric subjects between the ages of 6 and 17 and those patients had certain criteria to be included. They include the patients having had less than three bowel movements per week based on their own criteria. So that’s the inclusion criteria. Roughly when patients come into the pediatric study, it is not different than the adult studies. They come in roughly with about two or so spontaneous bowel movements per week. That’s like the baseline. So we’re looking obviously for clinical improvement. Oftentimes, we see an increase of one to two spontaneous bowel movements per week, and it has a clinically meaningful benefit for patients. So those are the metrics, but please don’t lose sight of the fact that there is currently nothing approved for pediatric functional constipation. So we really feel like there is a great opportunity. Obviously, data permitting, the discussion with the agency is clearly based on that Phase 2 study, where we did see a dose-dependent increase in the criteria around constipation, including spontaneous bowel movements as well as the Bristol Stool Scale Score for stool consistency. So certainly, with that data in hand, we look carefully with our partners and look for a good discussion with the agency. But we’re on track to do that in the second half of this year. So hopefully, that answers that question. Maybe I’ll stop there to see if I answered the question before I go to the IW-3300 question.

Yes, that answered the question.

Okay. So for IW-3300, again, we’re really excited about that program because for the first time, we’re going to be able to test this hypothesis that’s been in the medical and scientific community for decades, which is across all-time positive. So, you know clinically, when people have left arm pain, people are worried about cardiac pain, right? That’s sort of like this typical perception that happens in all of us. That also happens in interstitial cystitis and bladder pain syndrome, and that’s what we discovered with IW-3300 is as a really promising visceral hypersensitivity agent in all the preclinical models we tested, it reduced the visceral sensitivity. Given the colonic action of linaclotide that we know of, we’re first testing the rectal administration of IW-3300 just to ensure we have an adequate dose to prove this hypothesis because we will know with the rectal administration that we’re getting adequate exposure. Therefore, we certainly feel like we can achieve the dose we need, presuming the hypothesis proves to be valid to show a real clinical improvement in the pain sensation for bladder pain syndrome patients, because there is a lot of epidemiologic data that sort of correlates with IBS and bladder pain syndrome. So we think based on that, the proof-of-concept study is targeting this suppository. We’ve always known that an oral therapy would be useful in this population and probably preferred, and the current chemistry really supports the opportunity for an oral formulation. Again, we’re just testing the suppository because of the need to prove this hypothesis in clinical subjects in order to ensure we have adequate exposure. Real interesting signs as we’ve discussed this with urologists since there really are no good therapies currently available for bladder pain syndrome. So, we do have that data, and we appreciate your point. But from a longer-term vision, there certainly is an opportunity for an oral formulation.

Okay. Great, that’s very helpful. Thanks for taking the questions.

Hey. Thanks. So, just had a couple of questions. First, regarding business development and M&A. Can you just give us a refresher on how big of a transaction you could theoretically do? And what is the extent to which you could leverage to execute on a transaction? So, that’s number one. And just philosophically, how do you think about raising capital for M&A? And then secondly, I just wanted to get a refresher on the critical cap items for an OTC version of linaclotide. I know it’s something that’s been talked about in the past, but just a refresher on what needs to happen to get to a point where there could be a low-dose OTC version of the product? Thank you.

Thank you, David. There was some background noise. So, I will just – I think the first question is regarding our approach to business development in size and scale. The second one was about OTC and sort of the gate-staging items before we can actually achieve that, is that correct?

That is correct. Yes. Sorry about the background noise. Yes.

Yes. So, we are having ongoing discussions with our partner, AbbVie, because obviously, we think there could be a huge opportunity for an OTC version of LINZESS given the fact that we have an extensive safety and tolerability database to show the drug is extremely safe and well-tolerated as well as highly efficacious. So, we initiated those discussions and we are progressing. We think there is an opportunity because there are regulatory metrics in that space in terms of other considerations for OTC. So, we definitely think there is an opportunity. We think they may evolve around the concept of occasional constipation because, you know, as these transition to OTC, we put them in patient-friendly language and have an extensive safety database. So, we think based on response events, along with the current data we have with LINZESS and the medical need sort of out there, we think there is a huge opportunity. We are initiating those discussions, and we can give you more details as they materialize.

Mike, maybe you can take – Dave, this is Tom. Maybe you can take a minute and talk a little bit about the issue of the box warning and why that’s a key step as we move forward. The team has made tremendous progress already on kind of what is the path forward to get that result.

Yes, certainly. So, obviously, again, as I mentioned, safety and tolerability are key elements for the OTC approach. And as you know, last year, we had a great milestone event with the agency in the removal of the large majority of the warning and contraindication present on the prior LINZESS label. The prior label actually included the age population subjects 18 years and under. Through the last year of our post-marketing studies in pediatric patients, we generated a significant amount of data in pediatric patients, primarily within the ages of 2 years to 18 years. As you know, we have done a study in IBS patients from 7 years to 17 years. We have done a study in functional constipation in patients 6 years to 17 years. And we have also recently completed a functional constipation study in 2-year to 5-year-olds. We submitted all that data to the agency and in their review, we also proposed the modification to the warning and contraindication, and the agency was very supportive. That led to the current label which really only restricts for the 2 and below age category. Please note, we are currently not approved for pediatric patients. This was based on the warning language that was originally proposed in the label based on preclinical data and non-clinical data. So, with this delivery on clinical data in 2-year-olds to 18-year-olds, we were able to drastically remove a lot of the language in that population, but it still remains for 2 years and below. We think that’s critical, obviously, because the goal eventually is to remove the entire warning. We do think going forward, as we generate more data in the pediatric population, we will have ongoing discussions with the agency, and we do feel that removal is quite possible because the real point here is that it now is proven what was a theoretical risk based on preclinical data at launch with a significant amount of pediatric data we have, which was that pediatric patients might be sensitive to GC-C agonists and have an adverse event with over-secretion or dehydration and severe diarrhea, and we have not seen that in pediatric patients. In fact, what we have observed is that the dose needed in pediatrics is actually in line with what we use in adults. Therefore, the dose that we are focusing on for the functional constipation study is actually 72 micrograms for that Phase 3 program.

Great. With respect to our business development activities, I would say, look, we are very focused on creating value here for shareholders at Ironwood. The bar for pursuing a transaction from our perspective is very high. As you are well aware, David, in this environment, capital and cash preservation are very important. We still very much take stewardship of the fact that we have around $250 million this year or so of EBITDA that we are going to produce and have roughly $600 million in cash on our balance sheet. We want to be stewards of all of that. Our approach is to be value investors. If we can find opportunities in a market that’s potentially dislocated to create value, we will do it. But I think it has to really work for us. And I think you have seen commentary from other CEOs during the recent weeks of earnings calls, talking about where expectations are from sellers and how they potentially haven’t moderated again. I would just point you to that. From a size and scale perspective, I would also say, look, it really just depends on whether or not we see value. It depends on the opportunity set and whether or not we think we have the right capabilities to execute.

I think the other thing, Tom, I might want to comment on is that we are seeing a lot of opportunities – attractive opportunities. I mean CNP-104 is a classic example of a potential game changer in a very high unmet need market where we could really make a difference in the marketplace and certainly make a difference for Ironwood. So, I think we are encouraged with what we are seeing. Sravan has done a tremendous job dealing with the capital markets and his expertise in the capital markets. The bottom line is that as Sravan mentioned, the bar is high. We just want to ensure we are making very good, thoughtful goals as we proceed.

Very helpful. Thanks guys.

Thanks, David.

Hi. Thanks. Tom, could you talk a little bit more about this pediatric study? How many patients have you enrolled in this pediatric study? And I am sort of wondering, assuming the data is positive, would this data – would you go to the FDA and see if the data could be leveraged to remove the black box warning from your current label in the pediatric setting? And I know its pediatric patients less than 2 years of age that the black box refers to.

Yes. So, thanks for the question. Good clarification. The current study that I am addressing is in functional constipation in 6-year-olds to 17-year-olds, and it is a Phase 3 study that we designed in collaboration with the FDA with the ultimate goal of potentially submitting an sNDA for approval of functional constipation in 6-year-olds to 17-year-olds. So, that is the goal. That study is currently ongoing. It’s a large study because it actually includes some safety data in IBS patients. We have roughly about 460 patients, and there are other details on ClinicalTrials.gov. It’s actually a 12-week study, and it’s a change from baseline in spontaneous bowel movements over a 12-week period using the weekly average SBM frequency. Again, it’s a change from baseline, so it’s compared to their baseline, which is a two-week running period where they obviously have to be established with their criteria of less than three SBMs per week. We do think that if we could have a clinically meaningful effect and statistically significant evidence in that study, that there is a very real opportunity to have a discussion with the agency or a label change to include the indication for functional constipation in pediatric patients. Now, that’s data permitting; the study is still ongoing. We will compile all that together in the latter half of this year. We also obviously will have those discussions with AbbVie, but we are clearly on the same page strategically with AbbVie with that approach. That’s the current focus on the functional constipation component. How that relates to the warning, we already don’t have the 6 to 17-year-olds in the current warning language; it only pertains to the 2 years and below population. So, we will aggregate all of our pediatric data to have further discussions to ultimately get that part of the label removed, and all pediatric data helps. However, we will likely need data in the less than 2-year-olds too to have that discussion for complete removal.

Okay. That helps. Thanks for the answer Mike.

Great. Many of my questions have been asked already. But maybe just a little more on LINZESS. I am just curious, how much room do you think there is to cut on marketing expenses without significantly impacting revenue? I mean is that a discussion that you are having with AbbVie in the current environment?

Yes. So, Tom, do you want to try and answer that? Yes. Boris, I mean that’s an ongoing discussion. We have continued to throttle back particularly on professional promotion, which is a big, the second biggest expense line on the brand P&L. The thing that’s remarkable is the strength in the market leader position is still enabling the brand to grow even though we have dramatically pulled back on personnel promotion. We constantly evaluate that and we will be taking another look at it probably mid-year to see will we continue to throttle back on that expense. The other piece is we are also looking at the media buy. One of the real advantages of having AbbVie as a partner is they have such strength regarding media discounts, which has really helped the bottom line, but we will continue to look at that as well. So, I think there is opportunity to continue to expand the markets and make a more profitable brand, and we will continue to refine that with our finance colleagues across the two organizations.

Alright. Thank you for taking my question.

There are no further questions at this time. And that concludes today’s conference call. You may now disconnect.
